Let's divide 80840329 by 803
We want to divide 80840329 by 803.

Step 1:
If we divide 8 by 803, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 803

Let's proceed to step 2:
The number 803 fits into 80 0 times, leaving a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Fetch the next digit (8) from the dividend, attach it to 80 and continue: 808 / 803

Step 3:
808 divided by 803 is 1 with a remainder of 5.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 803 from 808 and we're left with 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 803

On to step 4:
If we divide 54 by 803, we get 0 and a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 54 to get 54.
Fetch the next digit (0) from the dividend, attach it to 54 and continue: 540 / 803

Moving on to step 5:
803 can be fit into 540 0 times, resulting in a remainder of 540.
Write down 0 as next digit of the result. 
Result so far: 100.0
The remainder is 540 after subtracting 0 from 540.
Take the next digit (3) from the dividend and append it to 540, then repeat: 5403 / 803

Step 6:
803 can be fit into 5403 6 times, resulting in a remainder of 585.
Write down 6 as next digit of the result. 
Result so far: 1006.0
Deduct 4818 from 5403 and we're left with 585.
Include the next digit (2) from the dividend after 585, then repeat: 5852 / 803

Moving on to step 7:
If we divide 5852 by 803, we get 7 and a remainder of 231.
The next digit of our result is 7. 
Result so far: 10067.0
Subtracting 5621 from 5852 leaves us with 231.
Fetch the next digit (9) from the dividend, attach it to 231 and continue: 2319 / 803

Let's proceed to step 8:
The number 803 fits into 2319 2 times, leaving a remainder of 713.
Use 2 as the next digit of our solution. 
Result so far: 100672.0
If we subtract 1606 from 2319, we get 713.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7130, and continue the process.

Going ahead to step 9:
7130 divided by 803 is 8 with a remainder of 706.
Use 8 as the next digit of our solution. 
Result so far: 100672.8
If we subtract 6424 from 7130, we get 706.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7060, and continue the process.

Going ahead to step 10:
803 goes into 7060 8 times with a remainder of 636.
The number 8 becomes the next digit in our result. 
Result so far: 100672.88
Subtract 6424 from 7060 to get 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

The quotient of the division is 100672.88, and the remainder is 0.636.
